I'll be in the Bakersfield/Tehachapi region this fall and could check out your CFI. I hope for your sake that you've sorted out the situation by then. After a number of hours instructing in the 152/172 the transition to the tri was not an issue. As others have said, I'm surprised the insurance company is being so troublesome. I insured with travers insurance out of St. Louis. Insured me in the pacer with no check out. I made sure I got one anyway.
